Maintaining Mag....

[Cal_stir]

i was using IO and switched to H2Ocean but i did not like it, you have to mix the dry mix before you use it because it settles out, i also found it left a lot of residue in my container and left a reddish brown residue on my sand bed, i have switched to IO Reefcrystals now.
I dose mag daily with a dosing pump, still had to dose with H2O but less, i dose 20ml/day with reefcrystals which tests @ 1200ppm mixed and it maintains my mag at 1350ppm
